vA further object of the invention is to provide a valve structure ofthe character mentioned equipped with additional means whereby a sprayhead may be easily attached thereto and readily operated to dischargeliquid at the desired temperature.

A still further object of the invention is to provide a valve structurecapable of being easily and minutely operated to determine thetemperature of the liquid within the valve las well as the pressure ofnow, with additional means to determine the rate of low or pressure inthe discharge spout.

A still further `object of the invention is to provide a valve structureembodying means whereby the rate of dow as well as the temperature ofvthe mixture within the valve may be regulated and set, with additionalmeans Ito determine the rate or pressure of ow from the spout at thetemperature already determined by the initial regulating means.

A still further and particular object of the invention is to provide aunitary valve of the character generally set forth which is of extremelysimple construction, which involves but few simple and readily assembledparts, which has its several parts so constructed and arranged las toinsure proper operation at all times, and to minimize the opportunityfor wear, breakage or derangeme'nt, which is positive in all of itsseveral action-s, and which prove highly effective and eicient inpractice.

4With the foregoing objects in view, together with others which Willappear as the description proceeds, the inven- -tion resides in thenovel construction, combination and arrangement of parts, all as will bedescribed more fully hereinafter, illustrated in the drawing, andparticularly pointed out in the claims.

The faucet of my invention may be used in connection with wash stands orother bathroom fixtures as well as with basins, kitchen sink-s or otherapparatus, with or without -a spray head connection.

ln carrying out the invention, I provide an elongated housing ofsubstantially hollow cylindrical form indicated at 10, the outer surface`of `which is provided with threads as shown to accommodate lower andupper clamping nuts 11 and 12, whereby the housing may be rigidlysecured within an opening 13 in la wash basin or wash stand portionindicated at l14. This housing is of tubular formation, the inner wallof which is of reduced diameter as at 15 to provide a concentric mixingchamber 16 with an abrupt shoulder 17 at its upper end Where it joins orcommunicates with the interior of the housing portion 10. The mixingchamber 16 is dened at its lower end by an -annular shoulder 18 whichprovides a valve seat determining the upper end of a liquid supply inletcharnber 19 concentric with the housing and yof less diameter than themixing chamber 16. The lower end of the inlet chamber is closed by thescrew plug 20. The inlet chamber communicates with hot and cold ports21-22 within the nipples 23 projecting laterally in diametricallyopposite directions from the lower end of the housing. lt will beunderstood that these nipples will be connected to the hot and coldwater pipes of the Water system. Arranged concentrically within `thehousing thus defined is an inner housing, core or sleeve indicatedgenerally at 24, This sleeve has its lower portion of substantially thesame external diameter as the internal diameter of the mixing chamber16, and is provided adjacent to its lower end with an outwardlyextending flange 25 to seat upon a lgasket resting upon the shoulder 17within the housing 10. The sleeve '24 is also provided with `a secondannular flange 26 spaced from the flange 25 and which constitutes a seatfor the reception of a gasket 27 to be engaged by the annular packinggland `or nut indicated at 28 having external threads as shown to engagewith similar threads upon the interior of the housing 1li at the upperend thereof. The exterior diameter of the core or sleeve 24 issubstantially reduced between the flanges 25 and 26 as indicated at 29,whereby to provide an elongated water `jacket 36 between the interiorwall `of the housing 10 and the exterior wall 29 of the sleeve 24.

The upper end of the sleeve or core 24 receives one end of the rotatableswing spout 31. This spout is of conventional form and is provided atits inner or attaching end with a circular opening to rotatably enclosethe upper end of the sleeve 24, being maintained thereon =between thespaced nuts 32 and 33 and is sealed against leakage by the spacedwashers or gaskets indicated at 34. The opening 35 in the swing spoutcommunicates with the interior of the core or sleeve 24 by spacedopenings 36 radiating from the sleeve as shown.

Arranged concentrically within the longitudinal passage 37 in the sleeveor core 24 is a shaft 38 of smaller diameter than the internal diameterof the core, the said shaft having an enlarged circular head 39 on itslower end disposed within the mixing chamber 16. This head is of lessdiameter than the interior diameter of the mixing chamber, and haswashers or gaskets 40 and 41 on its upper and lower ends to seatalternately, as the shaft 38 `moves longitudinally, against the lowerend of the core or sleeve 24 and the shoulder or valve seat 18 at thebase of the mixing chamber 16 respectively. The extreme lower end of theshaft 38 has secured thereto as by the screw 42 the upper end of a bellcylinder 43 having its external surface snuglyY engaging the walls ofzgssaosl the-inlet chamber 19. Theopposite sides of this Vcylinder areprovided with openings 44to communicate at predetermined times with theports 21-22 constituting the hot Y and coldV water inlets from thesystem, in a mannerY to be more fully describedhereinafter. The upper orclosed. end of the bell cylinder 43 is provided with ports.45'

which establish communication between the interior, of thetbellcylinder'and the mixing chamber 16.

inwardly of its ends the shaft 38 is provided with al screw thread 46 toengage complementary threadsupon the interior of the core or sleeve 24,Vthe pitch of these threads being suchthat limited rotary movement of theshaft will cause the latterto move the valve head'v 39.10 either closedupper or lower positions or'to intermediate open position within theYmixing Vchamber' 16.. This thread Vinner walls of the core or sleeve 24immediately below the laterally disposed ports 36 in the said sleeve orcore. This valve member 48has anexternal thread S2 which engagescomplementary threads in the gland member 33, and the crown handle 53encircling the shaft 38 is secured by threads, as shown, to the saidvalve member 48. It is obvious from this construction that the valvememberl 48 is movable longitudinally upon the shaft 38 and independentlyoftheY saidshaft so as to move the gasket 50 `either downwardly in tightengagement with Vthe seat 51 or reversely in anA upward direction todisengage the seat and to establish communication between the internalopening 37'of the core 24 through the ports 36 withthe.y

opening 35in the swing` spout.k Theoperations of the crown handle andtheparts associated therewith are" independent of any movement of the shaft38.y In other Words, theY valve member 48 may be moved'either to closedor-open positions without disturbingthe shaft 38 and, conversely, theshaft 38 may be rotated. without in any way aiiecting the valve 48.

Arranged within theside wall of the housing vis,an

outwardly extending nipple 54 shown in the present instance as closed bya plug 55. This nipple `communicates as by the opening 56 with the waterjacket 30 within the housing 10. This nipple is provided for theattachment of a spray connection if such is desired.

With reference now particularly to Fig. 2 of the drawing, it will beobserved that with the handle 47.swungl to the extreme left, the shaft38 has been rotated to such Cit degree that the openings 44 in the bellcylinder 43- are out of communication with both ports 21 and 22,whereupon no liquid may enter the inlet chamber and the valve is closed.The next position shows the shaft 38 rotated to such extent that one ofthe ports or openings 44 is in communication with the inlet port 21 topermitV full flow from that port while the opposite port 22 is closed.

. The next or intermediate position of lthe handle 47 shows the bellcylinder 43 moved to Vsuch position that the lateral openingsl 44therein'are in registry with both ports 21`and 22 where an equalquantity of liquid ofboth temperatures is being fully admitted. The nextposition shows the bell cylinder moved `to close port 21 and to openport 22while the nal position atthe right showsY the bell cylinderinsuch position that both of the inlet.`

ports 21-22 are closed. It will beunderstood'by manipulatiugjthe-handle47 the shaft 38-may, be rotated-tof positionsintermediatethose shown in FigaZ in ordergto accurately determine :thevtemperature -inthe jwater to' ybeA admitted to the inlet chamber as wellas to govern the rate of'flow.

It will be observed that the interior diameter of the sleeve or core 2.4is greater than the external diameter of the shaft 3S enclosed by thissleeve which provides the channel 37V extending throughout the length ofthe said sleeve, interrupted only'by the complementary threads upon theshaft and sleeve. Thesaid sleeve near its lower end and Vbelow thethreads-isprovided ywith.laterally` disposed ports or openings 57through which liquid in the mixing chamber 16 passes into. the waterjacket 30 when the valve head 39 uncovers theseat` 40, vandadditionalupper lateral ports or openings 58" are providedii'n the said core orsleeve 24 abovethe complementary threads to enable the liquid to passfrom the water jacket 30 back into the channel 37.
